' s claims. (C1. 51-213) My invention relates to a sharpening stone oiler and support and has for its principal object, to provide a relatively simple,.practical and inexpensive receptacle that serves as a container for a sharpening stone or stones with a body of oil in which the stone or stones are submerged while not in use and,'said receptacle alsoserving asl a support for holding the stonev infelevatedposition while in use. j

Further objects of my invention are, to provide a skeleton frame that receives and holds in proper assembled relation two sharpening stones which may be of diierent degrees of tex- 'A ture, for instance,y one ine and the other coarse,

further, to mountl on the ends of said frame ,pivoted or hinged members that function as handles and supports for the stone. carrying lframe and further, to construct the `ends of the receptacle so that the handles or supporting members may be applied thereto in different'positions, so

as to maintain the stones within the-receptacle entirely submerged in 4the oil thereinor, to hold the stones elevated within said receptacle in or-` der that the tools to be sharpened may be conf veniently rubbedy on the upper surface of the' upper stone. y

A further object of my invention` is, to provide simple and eiicient means for lubricating bothmembers of `a duplex sharpening element and, to provide simple and effective means for reversibly associating same with a receptacle that functions as a container for'the liquid lubricant that provides a bath for both sharpening stonesy my invention, with a portion of the cover broken away. v

Fig. 2 is an enlarged vertical section taken on the line 2-2 of Fig. 1.

Fig. 3 is a vertical section taken lengthwise through the end portion of the housing and .show- 504mg the duplex sharpening stone suspended in elevated position in orderI to'bring the upper one of the stones into position for use.

Fig. 4 is a plan view of lone end of thetdevice andv showing the duplex sharpening stones in` 55 elevated position.

Fig. 5 is a cross section taken on the line 5 5 of Fig. 4.` n v Fig. 6 is a detail cross section taken on the Aline 6-,6 of Fig. 4.

' will,v produce a certain amount of friction to ancho'rv the container when'the same is placed on a smooth surface.

The upper portions of the side walls of` the container are bent inwardly and downwardly to 15 form inclined flanges I2 that serve to prevent the liquid lubricant within the container from splashingupwardly adjacent the side walls thereof and then running down the outer faces of said( side walls. A cover I3 formed of sheet metal 20 serves as a closure for the open upper end of thecontainer.

The vupper portions of the `end walls Aof the container extend a short distance above the plane occupied by the upper edges of the side walls and 25 the central portions of the `upper edges of said end walls are cut away to form openings i4, the upper edges of which curve downwardly from both'ends toward their centers and the corners of the materialforming the end walls just above 30 the ends of these openings I4 are cut away to form notches l5.

The distance between the vertical edges of the notches l5 is slightly greater' than the distance between the yends of the openings I4. 35

A sharpening stone supporting :frame is cornposedl of pairs of side rails lli, preferably strips of metal L-shape in cross section, with the horizontal flange of one rail lying directly on top of the horizontal flange of theother rail and these l4:0 two sets of rails are tied together at both ends p and'at one or more intermediate points by transversely disposed bolts or screws il.

The frame thus constructed serves as a support for a pair of sharpening stones i8 which 45 stones are positioned between and clamped by the vertical flanges of the pairsof rails i6. The thickness of these flanges is substantially greater thanthe width of the fianges that clamp the sides of said stones. f

The sharpening stones may vbe natural oil stones or they may comprise homogeneous blocks of pulverized or powdered abrasive substance, such as emery or carborundum, the particles of which are bonded to each other by means ofa 55.

moisture proof adhesive and the two stones have different characteristics, that is, one stone may beformed from fine particles of abrasive substance and the other stone formed from coarser 5 particles of abrasive substance.

Substantially T-shaped members I9, each formed from a single piece of sheet metal provide handles for lifting and reversing the position of the sharpening stones and said members also serving as hooks for suspending the stones within the container III. The inner end` of the central member of each combined handle and hook is provided with a loop 20 that receives one of the end bolts I'I and the connection between these parts is such as to enable the combined handle and hook to swing freely on the bolt. 'I'he outer ends of the members I9 terminate in hooks 2l that are adapted to engage over the upper ends of the end walls Il! of the container when the sharpening stones occupy their lowermost position within said container as illustrated in Fig. 2. The width of each member i9 is slightly less than the space between the vertical edges of the notches l5 in the upper portions of the end walls and, formed in the sides of each member I9 adjacent the loop 20 on the inner end thereof are notches 22. The distance between` the inner ends of the notches 22 is slightly less than the distance between the ends of the opening It in the-end wall.

As a result of the construction just described, the members I9 vmay be used as handles to lift the sharpening stones from their lowermost position in the container, so as to position the uppermost one of said sharpening stones above the top of the container In and wholly above the body of oil within said container and to maintain the stones in this position, the members I9 yare swung outward and downward and manipulated so that the notches 22 engage the portions of the end walls of the container just beyond the `ends 0f the openings I4 as illustrated in Figs, 3, 4, and 6, and'thus the sharpening stones will be firmly held in their elevated position.

To reverse the position of the sharpening stones or turn the same upside down, the members i9 are engaged and the stones lifted entirely out of the container and after being reversed in position, said stones are returned to the container.

openings I4 facilitates this reversing of the sharpening stones and during such` reversing action the bottom edge of one of the notches 22 rides on the curved lower edge of said opening I4.

While not in use, both sharpening stones occupy their lowermost position within the container and when so positioned, both stones are entirely submerged in the body of oil within said container. While thus submerged, the stones are suspended by the members I9 with one hook 2I of each pair positioned in the space between the notches I5, thus providing a firm and substantial suspension means for the stones and their frame.

By completely subrnerging both stones in oil while said stones are not in use, practically all particles of metal removed from the tools that are being sharpened on the stones will be dislodged from the stones and passed by gravity to the bottom of the container.

To enhance this dislodgement of the particles of metal from the stones, the same should be manipulated after use so that the stone last used occupies a position in the lower portion of the 715y container and, thus the particles of metal will The curving of the lower edges of theV as a result of the lubricating action of the oil drop from the stone onto the bottom of the container.

Thus it will be seen that I have provided a sharpening stone oiler and support that is rela- 5 tively simple in construction, inexpensive of manufacture and very effective in performing the functions for which it is intended.

It will be understood that minor changes in the size, form and construction of the various 10 parts of my improved sharpening stone oiler and support, may be made and substituted for those herein shown and described, without departing from the spirit of my invention, the scope of which isset forth in the appended claims. 15
